Generally, the more an underlying terrain deviates from being flat, uniform and homogeneous, the less that classical theories and models of the atmospheric boundary layer hold. At times this leads to high uncertainties in turbulent flux predictions, and at ...
In this article, we present 10 experiments carried out in a steep, shallow water ume made of an erodible bed of natural, uniform gravel. We simultaneously recorded bed load particle motion, bed and water elevation using two high-speed cameras. Particle tra ...
The objective of this paper is to examine the importance of sediment diffusion relative to advection in bed load transport. At moderate bottom shear stress, water turbulence is too weak for picking up and keeping particles in suspension and so shallow wate ...
The subject of small-scale marine sediment mechanics is an area of active research, motivated by its key role in beach and shelf processes. Much of the existing small-scale work has focused on two-phase flows and particle behavior at the sediment interface ...
Although simplified methods have been proposed to allow for group effect and soil-pile-raft interaction, most of them are concentrated on one type of loading rendering the applicability of these methods rather limited to cases under such loads. In the case ...
Significant progress was made these last decades in the development of hydrogeological methods. However, these new methods are still very little used in the problematics of unstable slopes, mainly because of the hydrogeological complexity, which characteri ...
Tractor traction tyres interact with soil by a system of normal and tangential stresses along the soil-tyre contact surface. In this interaction both soil and tyre deform according to their own stress-strain relationships. Soil deformation results in the f ...
The behaviour of the pile-soil interface is important for the response of floating piles in terms of displacement and lateral friction. Regarding energy piles, which couple the structural roles of deep foundations with the principle of shallow geothermal e ...
This paper explores the challenges of model parameterization and process representation when simulating multiple hydrologic responses from a highly controlled unsaturated flow and transport experiment with a physically based model. The experiment, conducte ...
In temperate forest ecosystems, soil acts as a major sink for atmospheric N deposition. A 15N labeling experiment in a hardwood forest on calcareous fluvisol was performed to study the processes involved. Low amounts of ammonium (15NH4 +) or nitrate (15NO3 ...
